In version 2.16 the not visible setting of sets does not seem to get exported, and all imported sets become visible. Is it possible to get around this or the only way is to make the imported sets not visible in the homework set editor?
The issue with this is that we have a lot of sections using LTI to get student accounts into WeBWorK from Blackboard where all visible sets are automatically assigned to students at automatic account creation time.
